Tim,
Take a look at the RACOM page on the RR Wiki (
http://wiki.radioreference.com/index...MN,_NE,_SD,_IA). The section on the system confifiguration shows the different site plans in use.
According to the db, Oakland's site site ID is 7 (the last two digits of the site number), which means plan Q. You should be able to match the in-use frequencies at your site with the LCNs in the site plan.
I hope that helps. Please don't hesitate to let me know if I can assist further.
Tony
